                                A diagram in Ignace-Gaston Pardies's objections to Isaac Newton's theory of light and colour, in a letter to Henry Oldenburg dated 3 April 1672 (EL/P1/75/003). Oldenburg sent on Pardies's criticism to Newton on 9 April 1672, and Newton wrote a reply (dated 13 April). Both letters were read at the meeting of the Royal Society on 18 April 1672, and published in Philosophical Transactions of the Royal Society, vol. 7, no. 84 (June 1672).

[...] A letter from father Pardies the Jesuit, professor of mathematics in the college of Clermont in Paris, dated there April 9, 1672, N.S. containing some objections against Mr. Newton’s theory of light and colours. A letter from Mr. Newton, dated at Cambridge April 13, 1672, containing an answer to the objection of the said Jesuit’ (Birch, 3:43).
